Background shows as clear even though it is set to white

There are two options regarding loading portfolio/project showcase slides: using AJAX or regular loading.

The problem is caused by the fact row's background options/attributes are not loaded with AJAX

If you select regular loading you will not have any difficulties with visual composer rows styles.

If you want to keep the nice inline effects and you select loading showcase slides with AJAX, visual composer is bypassed and you will not see row's styles.

To solve this you need to add the CSS styles as raw html content at the end of the slide content. 

As step-by-step guide:

A. press Classic Mode Visual composer button 

B. you will see a in the content several  .vc_custom_.... codes

C. copy them

D. open the raw html at the bottom of the posts content

E. Paste it there inside 

<style data-type="vc_shortcodes-custom-css" type="text/css"> ... </style>

That's all. 

If you don't want to bother with these steps set 'Load Slides Content With Ajax' to 'No' in portfolio page options
